Open your web browser and navigate to the Skype’s official website. When the homepage opens, you need to click the “Share” button present at the top-right corner of your screen.
You will now see a blue button that says "Preview Message". You will have to click on the button present right next to it, that says "... or send to more friends".
You will now be taken to the "Share Skype with a friend" page, where you will have to fill out a form. The form will require you to enter your name, username, and the message which you want to send with the invitation, that you are sending to your friends.
You will also be required to enter the name and email addresses of your friends you want to notify of Skype.
If you don't want to send any particular message, Skype will forward a self generated message, inviting your friends/family on your behalf.
Go through all the details that you entered in the form and once everything feels correct, click the "Send this” button. Do not close your browser yet, as the invitations still have to be sent.
The next page that you see on your screen will be a preview of the message the your friends will see when they will get an email about your invitation. If you find an error, click the “Go Back” button and make the necessary changes. If everything looks good, click the “Send it” button, and your invitations for downloading Skype will be sent to all the friends.
A confirmation page will now appear on your screen, telling you about the invitations that you sent. You can now wait for your friends to open their emails inboxes and download Skype after reading your invitation.
You can talk to your friends on Skype, free of cost, after they download the free application and create an account on Skype.
